Menopause, or the cessation of menstrual periods, generally occurs in the 40s and 50s and marks the cessation of fertility, although age-related infertility can occur before then.
Silky lupine grows in northern areas from Washington and Oregon east to South Dakota. Tailcup lupine is found in Oregon, California, Idaho, Utah, Montana, and Wyoming. Velvet lupine is found in an intermountain region from Oregon to Wyoming. Silvery lupine occurs from North Dakota and Idaho south to Arizona and New Mexico.
I would like to add to this- Lupine grow much better where other plants from the legume family have grown. Some seed sources of wild lupine offer inoculant with their seeds. So depending what type you are trying to grow and where they will be growing you may have good or bad luck.
